   Token contract mirrors admin/css/variables.css: navy #1c2d4a brand,
   steel blue #1c539c for primary actions (white text), gold #d6a92b as an
   identity accent only (eyebrows, highlighted words, icon tints, rails).
   Every color resolves through a token so both dark-mode mechanisms
   (prefers-color-scheme and html.dark-mode) work without per-component
   overrides.
